摘要
目的探讨糖尿病肾病(DN)患者抗肾小球基底膜抗体(anti-GBM antibody)、抗心磷脂抗体(ACA)、尿酸(UA)和同型半胱氨酸(Hcy)检测的意义,为DN的诊断和治疗提供依据。方法收集174例2型糖尿病(T2DM)患者的血清,依据肾小球滤过率(GFR)和尿蛋白/肌酐比值(ACR)分为单纯糖尿病组(A组)、早期糖尿病肾病组(B组)、临床肾病组(C组)和肾功能不全组(D组)。采用间接酶联免疫法检测GBM和ACA,酶法检测UA和Hcy。结果进行统计学分析。结果 B组UA、Hcy和抗心磷脂抗体免疫球蛋白M(ACAIgM)水平高于A组,C组和D组UA、Hcy、GBM、抗心磷脂抗体免疫球蛋白G(ACA-Ig G)和抗心磷脂抗体免疫球蛋白A(ACA-IgA)水平高于A组,差异有统计学意义(P <0.05);C组UA和Hcy水平高于B组,D组UA、Hcy、GBM和ACA-IgA水平也高于B组,差异有统计学意义(P <0.05);D组UA、Hcy和GBM水平高于C组,差异有统计学意义(P <0.05)。GBM、ACA-IgA、UA和Hcy分别与ACR呈正相关(r=0.281、0.206、0.411和0.492,P <0.05),ACA-Ig G和ACA-IgM与ACR无相关性。结论血清UA、Hcy和ACA-IgM水平可提示早期肾损害,血清GBM、ACA、UA和Hcy可作为DN疾病进程的监测指标。
Objective To investigate the significance of anti-glomerular basement membrane(anti-GBM),anti-cardiolipin antibodies(ACA), uric acid(UA) and homocysteine(Hcy) in patients with diabetic nephropathy(DN), and provide a basis for the diagnosis and treatment of DN. Methods Totally 174 patients with type 2 diabetes mellitus(T2DM) were divided into four groups according to estimated Glomerular Filtration Rate(GFR) and anurinary albumin to creatinine ratio(ACR): diabetic mellitus group(A group), early diabetic nephropathy group(B group), clinic diabetic nephropathy group(C group) and renal insufficiency group(D group). GBM and ACA were detected by indirect enzyme-linked immunosorbent assay, and UA and Hcy were detected by enzymatic method.The results were statistically analyzed. Results Compared with A group, UA, Hcy and anti-cardiolipin antibodies immune globulin M(ACA-IgM) levels in B group were increased, and levels of UA, Hcy, GBM, anti-cardiolipin antibodies immune globulin G(ACA-IgG) and anti-cardiolipin antibodies immune globulin A(ACA-IgA) in C group and D group were higher than those in A group, the differences were statistically significant(P < 0.05). Compared with B group, levels of UA and Hcy in C group were increased, and levels of UA, Hcy, GBM and ACA-IgA in D group were also increased, the differences were statistically significant(P < 0.05). Compared with C group, UA,Hcy and GBM levels in D group were increased, the differences were statistically significant(P < 0.05). ACR was negatively correlated with GBM, ACA-IgA, UA and Hcy(r = 0.281, 0.206, 0.411 and 0.492, P < 0.05), but not correlated with ACA-IgG and ACA-IgM. Conclusions Serum levels of UA, Hcy and ACA-IgM may indicate early renal damage. Serum GBM, ACA, UA and Hcy may be used as monitoring indicators for DN disease progression.
